Having thus described my invention, I claim: 1..A spring socket attachment comprising a a the sleeve and supporting the sleeve, a contact metal disk, a tube extending upwardly from the center of said disk, a contact member mounted in said tube and slidable longitudinally therethrough, a spring urging the contact upwardly, spring arms extending upwardly from the periphery of said disk and having their upper ends bent inwardly into engagement with the outer wall of said tube and their intermediate portions.

crimped for engagement with the threaded shell of a lamp socket, spring fingers extending downwardly from said disk between said arms, a tubular sleeve suspended from said spring fingers} and spring arms extending downwardly from said disk for substantially the length of said sleeve and having portions intermediate their ends crimped to form teeth for gripping the base of a light bulb.

2. A spring socket attachment comprising-a metal disk, a sleeve extending downwardly from said disk, spring strips extending radially from the disk and bent downwardly from said disk and slit to form arms and fingers, the arms extending the length of said sleeve and crimped to form member extending upwardly from the center of said disk, and spring arms extending upwardly from the periphery of said disk between said strips and having their intermediate portions formed withprojections for engagement with the screw threads of a conventional lamp socket.

3. A spring socket attachment comprising a metal disk, a sleeve extending downwardly from said disk, spring arms bent downwardly from said disk and extending the length of said sleeve and having intermediate portions bent to form teeth for gripping the threaded base of a light bulb, a tube extending upwardly from said disk, 9. contact member slidably mounted in said tube with its lower end passing through the disk into the sleeve, a spring normally urging said contact member upwardly, and spring arms bent upwardly from said disk and having their upper ends bent inwardly into engagement with said tube whereby said spring arms are normally forced outwardly and their intermediate portions crimped to form threads for meshing with the threaded shell of 'a light socket.
